A biscuit that survived the sinking of the Titanic has been purchased by a collector in for $23,000, according to the BBC.

The biscuit, similar in shape and color to a cracker, was part of a collection from James and Mabel Fenwick, newlyweds who were beginning a three-month honeymoon trip to Europe in 1912 aboard the SS Carpathia, the ship that ended up rescuing survivors of the Titanic, according to auction house Henry Aldridge & Son.

The auction also included photographic negatives and a journal that offered a “unique snapshot” into the rescue of the 700 survivors.

The biscuit was said to be part of a survival kit that would have been found in a Titanic rescue boat.

“The Spillers and Bakers ‘Pilot’ biscuit was kept as a souvenir by the Fenwick’s,” the auction house writes on its site. “It was saved by Mr. Fenwick in a Kodak photographic envelope complete with original notation ‘Pilot biscuit from Titanic lifeboat April 1912.’”

The auction house called the relic the “world’s most valuable biscuit.” The item sold for around $8,000 more than it was expected to receive.
